EDWARD F. ACKERMAN, 0F PASSAIC, NEW JERSEY, ASSIGNORTO THE OKONITE COMPANY, OF PASSAIC, NEW JERSEY, A CORPORATION OF NEW JERSEY.

APPARATUS FOR COATING STRIPS OF TIN OR THE LIKE WITH RUBBER OR OTHER PLASTIC MATERIAL. I

To all whom it may concern:

Be it known that I, EDWARD'F. AoKnR- MAN, a citizen .of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain I -plastic rubber or other material, and one of the objects of the invention is to devise a structure which may be employed with the ordinary device which is at present employed for expressing rubber or other plastic material in tubular form.

In the accompanying drawings, which are to be taken as part of this specification, and in which I have shown a merely preferred form of embodiment of theinvention, 'Figure 1 is a front elevation illustrating an in the direction of the arrows, and Fig. 4'

l is a detail showing the manner in which the vertical controller member or gate is guided.

Referring to the numerals on the drawings, there is shown at 5 the head of a tube machine or other device from which the or controlling member 12, which has an inner face oppositely inclined to the inclination 11, as indicated at 14. The outer end or point 15 of the controlling .member 12 is in the line of a vertical diameter of the roller 9, and the controlling member 12 itself is guided in its vertical movements by means of tongues 16 engaging in corresponding grooves 17 in the member 7. A screw 18 is threaded through the end 6 of the head 5 and bears at its inner end agamst the con- I Specification of Letters Patent. Patent ed Sept, 5, 1916 Application filed October 5, 1914. Serial No. 864,999.

trolling member 12, so that as the screw is turned down the controlling member 12 is moved vertically downward. The screw 18 need not be positively connected to the mem-- ber 12 to move the latter upward, because the pressure of the material 19 against the inner face of the member 12 will tend to move the latter upwardly. The screw '18 may be provided with an indicating finger 20 cooperating with a scale 21 fixed on the head 5, asv shown in Fig. 2. It is evident that when the material 19 is pressed forward, that is, to the right in Fig. 2, by'any usual means, it will issue through the slit between the roller 9 and the point 15 of the member 12, simultaneously .with the strip 10. The thickness of the deposit of the material on the strip will depend uponv the vertical position of the member 12,

which as stated, is co ntrolled by the screw 18. It will be evident that if I desire to zontal adjustment for different widths of strips. In that figure, and in Fig. 3, incidentally, the'member 7 carries the vertically adjustable controlling member 12 as before, but it also carries a horizontally adjustable member 22, which slides over the member 7 by means of the tongue and groove'connection 24:, and also slides over the roller, 9'. The control of this horizontally adjustable member 22 is accomplished by means of a screw 25, which is threaded in a boss 26 carried on the member 7, and which issecured as at 27 in the member 22. By this construction it is obvious that I am enabled to secure adjustment for varying thicknesses of deposit of the rubber or other material on the strip and also adjustment for various widths of strip.

It will also be obvious that instead of the sliding controlling gate or gates I may use controlling members which are movable in some other way as, for instance, pivoted f coat strips of thin width it will be necessary members; Or, I might use devices, in the nature of eccentrics, so that when rotated to one position the openings controlled thereby would be of less extent, and when rotated to another positiontheywould be of greater extent.

Inasmuch as many changes could be made in the above construction, and many apparently widely 'difierent embodiments of'my invention could be made without departing fromthe scope thereof, it is intended that allmatter contained in the above description 'or shownin the accompanying drawings shall be interpreted as illustrative and.

' not in a limiting sense: It is also to be understoodthat the language used in the fol lowing claims is intended: to cover. all the generic and specific features of the invention "scope of the invention which, as a matter herein described and all statements of the of language, might be said to fall therebetween. 1

' I claim:

1. In a device ofthe kind described, a'

head through which material is adapted to be expressed, said head having an enlarged end, and a device securable in said enlarged end and including a roller, a member on .either side of the-roller and agate relatively movable 'with respect to the roller arranged between said members, whereby a slit may be defined between the roller and whereby aslit may be defined between the roller, the gate and the movable member.

3. In a device of the kind described, a

head through which materialis adapted to be expressed, said head having an enlarged end, and a device securable in said enlarged end and including aIroll-er, a member on i either side of the roller one movable, and a gate arranged between said members relatively movable with respect to the roller,-

said movable member arranged to slide over the face of said gate, whereby a slit may be defined between the roller, the gate and the movable member.

' 4. In a device of the kind described, a

head through Which material is adapted to be expressed, said head having an enlarged end, and a device securable in said enlarged --end and including a roller, a member on either side of the roller one movable, and a 5 gate arranged between said members relatively movable with respect to the roller, said. movable member arranged; to slide over the face of said gate, whereby aslit may be defined between the roller, the gate and the movable member and means for moving the said movable member and the gate.

5. In a device of the kind described, a

head through which material is adapted to be expressed, said head having an enlarged end, and a device securable in said enlarged end and including a roller spaced from said end over which a strip. of material is adapted'to be passed, arnember 'on either side of the roller, and a gatear'ranged between said members relatively movable with respect to the roller whereby a slit may be defined between said members, the-gate and the roller.

-6. In a device of the kind described, a

head through which material is adapted to r be expressed, said-head having an enlarged end, and a device securable in said enlarged end and including a stationary member and a movable member, a roller carried by the stationary member and a gate arranged between said'members and relatively movable with. respect to the roller whereby a .slit

' may be defined between the roller, the gate and said members. k

In testimony whereof I aifix my signature in presence of two witnesses.
